2 Claims. 1

This invention relates to a broadcasting seeder.

An object of the presentinvention is to provide a machine of the character described especially designed for broadcasting seed.

It is another object of the present invention to provide equipment of the character described which is specially designed to be mounted on a vehicle and which is of such construction that is adaptable for mounting ona tractoror .any other selected type ofmotor vehiclqand which may be readily operated from a power takeoff shaft connected with the vehicle motor.

More specifically the invention embodies a supporting frame, a hopper-like seed container fixed above the frame, an adjustable receiving hopper arranged to receive the seed from the container and provided with a hood-like discharge nozzle and impellers in said nozzle and operativel' y connected with the takeoff shaft for broadcasting the seed received by the nozzle from the seed hopper.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings wherein Figure 1 is a side View of the seeder, and

Figure 2 is a rear elevation thereof,

Referring now more particularly to the drawings wherein like numerals of reference designate the same parts in each of the figures, the numerals I, I designate upwardly converging rear legs and the numeral 2 designates similar upwardly converging forward legs. The front and rear legs are connected, at their upper ends, by suitable cross bars, as 3 and 4. These front and rear legs are anchored in fixed relation to each other by means of suitable cross bars, as 5, 5. Secured to the rear side of the rear cross bar 3 there is an upstanding plate 6 and secured to the forward side of the cross bar 4 there is an upstanding plate I. These plates have vertical slots, as 8, 8.

Extended through the respective bars 3 and 4 there are clamp bolts 9, 9 and ID, ID which eX- tend also through the slots of the plates 6 and I, and which have heads on their inner ends and clamp nuts on their outer ends whereby the plates 5 and I may be clamped in fixed position. By loosening said clamp nuts the plates may be adjusted vertically in an obvious manner.

The plate 6 extends up somewhat further than the plate I and its upper end is provided with a U-shaped notch in which the hopper II is seated.

his. h p r m y. f d s red; e welded to said plate and it, is further supported by means of. a bracket l2 which is secured thereto at one end and whose other end is suitably secured to the platel. I I I Mounted in suitable bearings in the plates 6 and? and extending rearwardly beyond the plate 6 there is an impeller shaft I 3,

The. lower endofthehopperll terminates in a discharge spout I4 through which the shaft 13 extends and fixed to this spout there is a rear-, wardly flared nozzlev I5. This nozzle may be. securely anchored in place vbysuitableside straps I6, I 6; which are secured, at their upper ends to the sides of thehopper II and at their other ends to thesides of said nozzle.

The free margins of the nozzle may bev braced, if desired, bycross braces I1 whose ends are secured to said margins.

The discharge of seed from the hopper II through the spout I4 in to the nozzle I5 may be regulated by a suitable vertically slidable gate [8 which may be secured at any desired point of adjustment by a clamp screw l9.

As illustrated the seeder is shown mounted on a motor vehicle 20 which is equipped with a power takeofi shaft 2| driven by the vehicle motor and which has a sheave 22 fixed thereon.

The shaft [3 has a small sheave 23 and a larger sheave 24 fixed thereon.

There is a driving belt 25 which is operable over the sheave 22 and is also operable over the sheave 23 when the unit supporting the hopper II is adjusted to its upper position but this belt 25 operates over the sheave 24 when said unit is adjusted to its lower position.

Within the nozzle l5 and fixed on the rear end of the shaft I3 there are the blades 26 which are set at the required angle to propel the seed rearwardly as seed are fed into the nozzle from the hopper I I.

There is a hopper-shaped container 21 for carrying a supply of seed to be broadcast. This container is located above the hopper II and is supported on the frame of the seeder by means of rear and front standards 28 and 29 whose lower ends are suitably secured to the legs I and 2 and whose upper ends are secured to the container.

The container has an outlet over the hopper II and secured to the lower end of the container there are the tracks 30, 30 in which a controlling gate 3! is slidable. The outer end of the tracks may be secured in place by the angle braces, as

32, 32, whose ends are secured to the container and to the tracks, respectively.

The gate 3| may be adjusted to allow the fiow of seed from the container 21 into the hopper in the quantity required, or said gate may be completely closed.

As the vehicle 20 moves along the shaft l3 and impellers 26 will be rotated and the seed will be fed from the container 21 into the hopper and thence into the nozzle [5 and the impact of the blades 26 against the seed together with the air current generated by said blades will broadcast the seed uniformly over a definite area and the quantity of seed being delivered may be regulated in accordance with the requirements of the situation.

The drawings and description are illustrative merely While the broad principle of the invention will be defined by the appended claims.

What I claim is:

'1. A machine of the character described comprising, a frame, standards fixed to and upstanding from the frame, a hopper-like seed container supported by said standards above the frame, front and rear plates vertically adjustable on the frame, means for securing said plates to the frame at a selected point of adjustment, a hopper beneath the container supported by said plates and adjustable with said plates, a downwardly and forwardly projecting spout on the lower end of the hopper which terminates in a forwardly and outwardly flared nozzle, a transverse shaft mounted in bearings in said plates and extending through said spout and axially into the nozzle, a source of power, rotatable means operatively connecting the shaft to said source for rotating ,the shaft, impeller blades fixed on the forward end of the shaft within the nozzle and set at 4 angles to broadcast the seed from the nozzle as the blades rotate.

2. A machine of the character described comprising, a frame adapted to be mounted on a motor vehicle, standards fixed and upstanding from the frame, a hopper-like seed container supported by said standards above the frame, front and rear plates vertically adjustable on the frame, means for securing aid plates to the frame at a selected point of adjustment, a hopper beneath the container supported by said plates and adjustable with said plates, a downwardly and forwardly projecting spout on the lower end of the hopper which terminates in a forwardly and outwardly flared nozzle, a transverse shaft mounted in bearings in said plates and extending through said spout and axially in the nozzle, impeller blades fixedbn the forward end of the shaft within the nozzle and set at angles to broadcast the seed from the nozzle as the blades rotate, said vehicle having a power take-off shaft and operative comiections between said shafts operative at either point of adjustment of said plates whereby the impeller shaft may be driven.
